Prophylactic norepinephrine infusion or leg wrapping for postspinal hypotension in elective caesarean delivery: A randomised, double-blind, placebo-controlled trial
BACKGROUND
Because of its alpha and beta agonist properties, norepinephrine infusion is currently being studied for the prevention of spinal hypotension during caesarean delivery. Vasopressor infusions are not always possible if there is an unavailability of infusion pumps. Leg wrapping with crepe bandage is an effective technique for prevention of postspinal hypotension and could be useful in resource-poor settings.
OBJECTIVE
The aim of this study was to compare the incidence of hypotension with norepinephrine infusion or leg wrapping with a control group in women undergoing caesarean delivery with spinal anaesthesia.
DESIGN
Randomised, double-blind, controlled trial.
SETTING
Single centre, tertiary level institute, India.
Study period 3 April 2018 to 31 March 2019.
PATIENTS
One hundred and forty-four women aged 19 to 40 years with a singleton pregnancy.
INTERVENTION
In group Leg Wrapping, crepe bandage was applied tightly from metatarsus to groin. Group Norepinephrine and the control group received sham leg wrapping. In group Norepinephrine, the women received a norepinephrine infusion according to their body weight, while group Leg Wrapping and the control group received a 0.9% normal saline infusion at a similar rate. All three groups received a 500 ml co-load of Ringer's solution over 15 min. Noninvasive SBP was monitored every 2 min until delivery, and every 5 min thereafter. Any hypotensive event (SBP
